MAINTENANCE PRECAUTIONS
 Do not permit acidic, caustic or abrasive fluids to be pumped through system.
 Periodically clean detergent inlet screen. This will ensure proper flow of water to the pump.
 High mineral content in water may adversely affect your machine and may require the use of a water softener
to ensure proper operation.
 NEVER run the pump dry under any circumtances. Doing so will cause exteme damage to the pump.
�
WARNING
FAILURE TO MAINTAIN HEAT EXCHANGER COIL MAY
RESULT IN A STEAM EXPLOSION WHICH MAY CAUSE
SERIOUS INJURY OR DEATH.
HEAT EXCHANGER COIL MAINTENANCE
 Hard water conditions may eventually cause clogging in the heat exchanger coil if left unattended. Scale deposits will compromise the heating efficiency and produce an unsafe condition over time. It may be necessary to descale coil.
 Scale buildup from certain detergents may eventually clog up the heat exchanger coil causing an
unsafe condition. Use only recommended detergents for better cleaning efficiency.  Black carbon deposits that collect on the outside wall of the heat exchanger coil may be a result of
using a poor grade of fuel or improper burner operation. Heating fuel should be void of water and
sediments to eliminate the possibility of sooting and compromising the efficiency of the coil.
MOVING, STORAGE
 Place machine in covered area when not in use to protect from elements.Protect machine from
freezing in cold temperatures by storing in a heated location.
ENGINE MAINTENANCE
 Every time (before start): Check oil level.
 First 8 hours: Change oil with SAE 30W High-Detergent Oil.
 Every 25 hours: Change oil if operating under heavy load or high ambient temperature.
Service air cleaner pre-cleaner.
 Every 50 hours: Change oil. Clean and inspect spark arrester if equipped.
 Every 100 hours: Service air cleaner cartridge, replace oil filter (if equipped),
Clean oil cooler (if equipped), Clean cooling system.
WINTERIZING
Non-float Tank Machines: To protect the machine from freezing temperatures while
storing or transporting, connect short length of garden hose (approximately 3 ft.) to
water inlet connection on machine. Remove the pressure nozzle from the wand and
insert the short garden hose end into a container of antifreeze. Place the wand into the
antifreeze container and start engine running machine until antifreeze appears from the
end of the wand. Turn engine “OFF” and replace pressure nozzle. Coil up hose and
move machine to storage area.

ELECTRODE SETTINGS
 Inspection of all wires, spring
contacts and electrodes should
be done periodically. �
WARNING
IF BLACK OR WHITE SMOKE VENTS FROM EXHAUST
PORT UPON STARTING EQUIPMENT, DISCONTINUE USE
AND ADJUST AIR BANDS BEFORE RESTARTING.
OIL BURNER AIR BAND ADJUSTMENT
RAMTEQ sets oil burners at sea level. Air bands may need adjustment at higher elevations to
offer eCHanced performance of the burner and extended life of the machine. ®
 Adjustment of burner is done with pump motor and thermostat
set to maximum. Loosen locking screw on air band, then close
band until black smoke vents up exhaust vent. Take careful note
of air band position when black smoke is first noticed. Slowly
open air band until white smoke vents, then turn air band halfway
back to where black smoke was first noted. Tighten air band
locking screw. When properly set, the unit should NOT have either
"black" smoke or "white" smoke during operation.
PUMP MAINTENANCE
 Fill crankcase to dot on oil gauge window per specifications with the specific oil created by the
pump manufacturer (i.e. General Pump Oil). Ensure the right oil for specific pump as it may vary.
 Change oil after 25 Hour Break-in Period.
 Change oil every Three Months or at 100 Hour Intervals thereafter.
UNLOADER ADJUSTMENT
 All RAMTEQ machines have the unloader correctly set at the the factory. Setting an unloader
is a difficult job without the proper equipment and training. Should the need arise to change the unloader
settings, please contact your local distributor.

Page Operating Instructions
LOCATION GUIDELINES
 Locate the machine on a solid and level surface so that engine and pump crankcase oil lubricate components properly.
Avoid areas where water can build up in the working area. Possible injury can occur caused by the surface becoming
slippery from water build up.
 Locate the machine in a well-ventilated area and away from flammable materials or fumes. Be sure ventilation warnings
are observed. Keep pressure washer at least 18” away from flamable materials.
 Locate the machine so the operator has easy access to the jetter/pressure washer and its controls. Locate the machine
so that it is protected from external damage.
 To prevent damage and excessive hose wear, locate the unit so that the hose does not cross traffic areas.
STARTING THE MACHINE
Following the steps below will insure successful operation:
 Read this manual completely before attempting to start the machine.
 Check the fuel tank and fill with a good grade of gasoline (87 octane minimum) for gas engines and a high quality diesel
fuel for diesel engines.
 Check the engine oil level and fill with SAE 30 weight high-detergent oil.
 Check the pump oil level and fill with SAE 30w non-detergent oil if needed.
 Check water tank to ensure adequate level of water required for the job.
 Pull trigger on gun until a steady stream of water comes out the nozzle. This purges any air in the system.
 Slide fuel switch to the RIGHT and slide choke switch to the LEFT (closed position).
 Turn ON/OFF switch (on engine) to “ON”.
 Open water flow to reduce back pressure in pump. Back pressure can overpower electric starter, preventing ignition.
 Turn key to start gas engine and allow RPM to develop.
 Let engine warm up for approximately 30 seconds and slide choke to “OPEN” position.
 Check for leaks in the system and cycle trigger gun to insure bypass is adjusted correctly. Repair any leaks and correct unloader adjustment if needed. Turn off machine before attempting any repairs.
 WARNING - Do not operate machine with less than 6" of water in the tank. Doing so may cause pump damage!
STOPPING THE MACHINE
 Turn engine to “OFF”.
 Pull gun trigger to release water pressure from system.
 Disconnect wand & gun assembly.
 Wind up pressure hose on hose reel.
CAUTION
 Always wear protective safety gear, auch as, but not limited to, rain coat or coveralls, rubber boots, face shield or
goggles, gloves and hearing protection.
 Do not run the machine for more than two minutes with the jetter water flow shut off (by-pass mode). This will over
heat the jetter pump and could cause injury to you.
 Do not run hot water thru this pump. Hot water will damage the pump, and will void the warranty.
